$variablesCount provides a quick way to check how many variables are active in the current execution context. This is useful for validation, debugging, and conditional logic.

Return Value

The count is always returned as a string representation of an integer (e.g., "3", "0", "15"). When used in numeric comparisons, BDFD will automatically coerce the string to a number.

Type Filtering

When a Type parameter is provided, only variables of that type are counted:

• $variablesCount — count all active variables (all types).
• $variablesCount[temp] — count only temporary variables.

Comparison with $listVar

While $listVar gives the names and values of temporary variables, $variablesCount gives only the count. Use $variablesCount when you need a numeric check (e.g., “are there at least 3 variables?”) without the overhead of formatting a full list.
